PAINT-BRUSH.

SPECIFICATION forming part of Letters Patent No. 298,166, dated May 6, 1884.

' Application filed January 1S, 1884. (Model.)

To all whom it may concern.-

ABe it known that I, JOHN FEANcis Bow- DIToH, of Revere, inthe county of Suolk, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Paint-Brushes; and I do hereby declare the same to be described in the following specication, and represented in the accompanying drawings, of which- Figure l is a side View of the brush; Fig. 2, a top view; Fig. 3, a section taken transversely of the ferrule; Fig. 4., a perspective View of the handle, cap, and tongue; Fig. 5, a section taken longitudinally of the ferrule.

In the annexed drawings, the letter A represents the handle; B, the bristles; C, the cap, and D the ferrule. In putting these together a hole is cut in a block of wood, afterward cap C and the handle A are driven through such hole :from the under side of the block and made fast in the latter. The block is then cut lengthwise on each side, underneath, forming a tongue, a, having the ilat or Vstraight sides b and the wedge-shaped point a', such tongue being thus formed of the lowerend of the handle and the ends of the block on each side of such lower end. The bristles B are bunched in a mass, and the ends to be inserted in the ferrule are provided with cement and then :inserted in the ferrule D. The wedges E E are then placed inside of the sides of the ferrule at the bottom, alongside of the mass of the bristles. These wedges are inserted with their thin edges cup into the ferrule alongside of the butt-ends of the bristles and their thicker edges c below, as shown in Fig. 3. The handle A, with the cap C, is then forced down into the ferrule from the top, the tongue a entering the mass of bristles, the wedgeshaped point facilitating such entrance. As

the tongue c enters among the bristles, it pushes them into two parts against the sides' of the ferrule D and the wedges E E. As the space between the thicker or lower edges of the wedges is smaller than that above the wedges or under the cap, the two portions of the bristles thus jammed by the tongue a are forced into two dovetailed portions, and will Y successfully resist any strain to pull them out of the ferrule. lIhe inner surfaces of the wedges crowd the bristles over against the wedge-shaped point of the tongue,holdi ng .the bristles thus firmly in a mass, and giving to the ag ends of the bristles on each side of I I am aware that a brush has been devised the handle of which has a wedge which comes among the bristles in the ferrule. Such wedge is shaped the reverse of the one shown in my device, being larger at its lower end.

I am also aware that a brush has been devised which is provided with a ferrule made conical inside or ilaring, and that the handle of the brush has a conical end which comes among the bristles in the ferrule.

Having thus described my invention,what I claim is The handle and cap` provided with the wedge-pointed tongue and the mass oi' bristles, in combination with the ferrule and the Wedges E, the latter being placed within the sides of the ferrule at the bottom alongside of the bristles, with their thin edges next to the butts of the bristles, substantially as described.
